Overview of Building external wall fire insulation material aerogel insulation felt

Aerogels are ultralight, highly porous materials known for their exceptional insulation properties, remarkable low density, and incredible strength-to-weight ratios. Often referred to as "frozen smoke" due to their ethereal appearance, aerogels are produced by replacing the liquid component of a gel with gas, typically through supercritical drying, which avoids collapse of the gel structure. Composed primarily of air (up to 99.98%), these materials exhibit a wide array of unique characteristics that make them valuable across various industries.

Features of Building external wall fire insulation material aerogel insulation felt

1. Extremely Low Density: Aerogels are some of the world's lightest solids, with densities as low as 0.001 grams per cubic centimeter.

2. Superb Insulation: They possess extremely low thermal conductivity, making them among the best insulators known to man, effective at temperatures from -270°C to 1,000°C.

3. High Porosity: With a porous structure that can reach up to 99.9%, aerogels have an incredibly large internal surface area, enhancing their functionality in absorption and catalysis applications.

4. Translucent to Transparent: Depending on their composition, aerogels can transmit light, giving them a unique semi-transparent or transparent appearance.

5. Mechanical Strength: Despite their fragile appearance, aerogels can be engineered to possess significant mechanical strength, capable of bearing considerable weight.

6. Chemically Inert: Many aerogels are chemically stable and resistant to corrosion, making them suitable for harsh environments.

Parameters of Building external wall fire insulation material aerogel insulation felt

Aerogel insulation felt is a type of insulating material that uses microgels to create an insulating layer between the surface of the insulation and air. The term "airogel" refers to the fact that the microgels in the insulation are made up of water vapor, which makes them highly resistant to heat transfer. The temperature coefficient of adhesion (Kt) of aerogel insulation feels is typically around -40°C per degree Celsius change in temperature. This means that it can withstand very high temperatures without losing its insulation properties. In terms of thickness, aerogel insulation feels is typically available in various thicknesses, ranging from 25mm to 100mm. The thickness of the insulation will depend on the specific application and the desired level of insulation performance. It's important to note that aerogel insulation felt may not be suitable for all applications due to its relatively high cost and lack of flexibility. It's also recommended to consult with a professional insulation contractor before installing this type of insulation material.

FAQs of Building external wall fire insulation material aerogel insulation felt

Q: Is Building external wall fire insulation material aerogel insulation felt fragile? A: Traditional aerogels are brittle and fragile; however, advancements have led to the development of "flexible" or "rigid" aerogels that maintain their unique properties while being more durable.

Q: How is Building external wall fire insulation material aerogel insulation felt made? A: Building external wall fire insulation material aerogel insulation felt is synthesized by replacing the liquid in a gel with gas without causing the structure to collapse. This is typically achieved through supercritical drying, where the solvent is converted to a supercritical state, allowing it to evaporate without forming liquid-gas interfaces that could damage the gel structure.

Q: Is Building external wall fire insulation material aerogel insulation felt expensive? A: Historically, aerogels have been costly due to their complex manufacturing process. However, with technological advancements and economies of scale, costs are gradually decreasing.

Q: Can Building external wall fire insulation material aerogel insulation felt conduct electricity? A: Most aerogels are poor conductors of electricity due to their porous, insulating nature. However, certain metal-oxide aerogels can display semiconducting or even conducting properties.

Q: Is Building external wall fire insulation material aerogel insulation felt environmentally friendly? A: Aerogels themselves do not pose environmental hazards, and their use in insulation can reduce energy consumption. However, the production process may involve chemicals that require careful handling and disposal.
